This is quite a group of people and cannot be overlooked. Worst case a solution will be found after the call centre is flooded with June applicants' calls.
If this helps at all, I clearly remember dating back to September last year, some June 5th - 15th (ish) people had problems receiving their AORs on time. Even when mid July applicants were receiving their AORs, this group of people were still watiing. That stirred quite some unrest on this forum. I looked at your current June spreadsheet, although it doesn't reflect what I stated above, I am 100% certain about my memory.
10 months later history seems to be repeating itself. Rather than being shocked, angered, or getting a high blood pressure, you may as well shrug it off and do something practical (say preparing for BOWP if your WP is coming to an end soon) while waiting for July to come and call CIC again.
